Specification of Letters Patent.

Patented Jury o, 1912i Application led March 20, 1912. Serial No. 685,109.

To all whom t may concern.'

Be it known that I, NORTH DowLrNe, a citizen of the United States, residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Portable Flash-Light Apparatus, of which the following is a specification.

My invention relates to an electrically cont-rolled fuse apparatus for firing powder to produce a flash-light for photographic purposes; and in such connection, my invention has for its principal objects, first, the constructive arrangement of the apparatus; second, the portable telescoping character of the apparatus; third, in conjunction with the telescoping features the convenient and quick adjustments of parts to position, without aecting circuit connections with the fuse point of the apparatus arranged to permit of the firing of powder therefrom; fourth, the provision of the apparatus with means to enable the testing of the circuit before firing the powder, thereby to be assured in advance of the firing of the powder that the apparatus is in required safe condition to fire the powder so as to produce a flash-light therefrom; fifth, the provision of such a portable apparat-us with a detachable battery, for furnishing1 the current for the fuse point adapted to lire the powder; sixth, the provision of such an apparatus with internal separable members as well as an eX- ternal sectional casing for providing conductors from a battery to the fuse point, in which is included an audible or sight testing device for the circuit prior to actual ring of the powder ;v and seventh, to the provision of such an apparatus with features and details in constructive arrangement to be hereinafter described and pointed out in the claims.

My invention stated in general terms, consists of a portable electrically actuated as well as controlled flash-light apparatus constructively arranged in substantially the manner hereinafter described and claimed.

The nature and scope of my present invention will be more fully understood from the following description taken in connecsaid invention. Fig. 2, is a vertical sectional view through the same, showing the detail arrangement of internal members thereof. Fig. 8, is a perspective view enlarged, of the powder container and fuse point located in the bottom thereof, showing one form of fuse point connections therefor. Fig. 4, is a view partly in vertical section through the powder container and fuse point connections of the same, and in broken sectional elevation the standard and internal telescoping members thereof in electrical connection with the fuse point of said container. Fig. 5, is a side elevational view of a broken section of the standard, and in side elevation a detachable battery and signaling device, showing the same in electrical connection with internal and external members of said standard and the electrical connections to a manual operating device. Fig. 6, is a perspective view of one type of a fuse piece, composed of recessed metal pieces having mica between them, for inserting about binding posts of the fuse point of the powder container of Figs. 3 and 4. Fig. 7, is a vertical sectional view through the manual operating device intended to be included in the battery circuit, showing the push-buttons for respectively, testing the said circuit before firing powder of the container from about the fuse point therein; and Fig. 8, is a diagrammatic view of a divided battery circuit in which a buzzer or other signaling device is included and with respectively, push-buttons for testing the device before firing, and for hashing powder from a container, included in said battery circuit.

Referring to the drawings, and particularly Figs. 1 and 2 a, is a tubular sectional casing constituting a standard, provided with a series of hinged legs al, connected by means of links a2, with a runner a3, in order to readily permit of folding the legs against the said standard, when the latter is not in ed to be adjustably held thereto by means of' t tightening screw a7, extending through a collar as, carried thereon, as clearly shown in Fig. 1.

ln the lower portion of the hollow standard a, is mounted a fiber or other insulatingA hollow plug a9, as shownin Fig. 2, and in which is mounted a hollow conductor 661, which is securely fitted thereto. The conductor alo, is insulated by means of a sur` rounding fiber sleeve a, from the outer cas-v ing of the standard a., as clearly shown ini Fig. 2. The conductor am, telescopes with a similar hollow rod C512, the upper end of which is split at (L13, and with inturned flanges so as to detachably engage a pear-v shaped device am, of a solid conductor rody 415, which latter is fixed to an insulating fiber plug al, in the upper section of the standard a.

b, is an insulated adjustable binding post extending through the liber plug a9, into' Thisy binding post is connected with a dry or other suitable battery, by means of an angular-l contact with the hollow conductor al.

shaped metal seat h1, Fig. 5, having an insulated bacl b2, arranged to support a buzzer"` or other signaling device ha, and a suitable The signaling de-` dry or other battery 64. vice d3, is in a divided circuit 1l, from the battery b4, to a push-button bs, extending from a holder b5, having leading therefrom a cord 56, all to be presently more fully eX- plained, whereby testing of the flash-light.: appliance can be had before flashing of the' powder from the container c, thereof. @,f represents a fuse point having binding posts c1 and c2, mounted on a fiber or other suitablef'insulating base c4. rThese binding posts by metal strips c5 and 0G, are respectively connected with the upper section of the standard a, and by an insulated screw-bolt c7, with the internalconducting rod @15, as` clearly shown in Fig. 2. On the insulating.

base ct, is adapted to be mounted an inclined trough es, in which powder is to be placed directly over the fuse point c, for flashing,` the same, as will be clearly understood from@ Fig. 1. The fuse point c, is established by means preferably of a cartridge d, consisting@ of two recessed pieces of suitable metal Z1? and cl2, bent over a strip of mica or the like,

alg, and so that the mica is exposed between the said strips or pieces, for example, as clearly shown 1n Fig. 5, or simply a piece of readily fusible wire, not shown, may be used and placed in connection with the binding posts c1 and c2, of the fuse point c, in the powder trough 0S, so that when the current is applied to the cartridge at the fuse point c, the powder will be instantly flashed.

ln the head of the push-button device b5, is provided a manual push-button 57, which when depressed actuates the battery circuit to i'ire the powder of the container 08, and

- on one side is provided a manual push-button (7)8, which when depressed actuates the buzzer or other .signaling device 53, to test the device, before firing of the powder for producing a Hash-light therefrom.

In Fig. 8, are shown the circuits .10 and 12, from the battery b4, to the push-button 57, and its contact, and in which circuit 12, `is included the binding posts c1 and c?, with the fuse-point c, and at which point the powder is placed, in a container, to be flashed therefrom. From the battery b4, the circuit is divided through the buzzer b3, to the push-button 3, when the line 1l, is closed with the line 12, to actuate the buzzer for testing the device, without affecting the circuits 10 and 12, through the binding posts c1 and c2, with the fuse-point c, to lire the powder of the container thereat.

Having thus described the nature and objects of my invention, what l claim as new and desire to secure by Letters Patent is 1.
